Dark Chocolate & Hazelnut Protein Cakes

I made these cakes for a dear moustachiod wizard I went to meet in London yesterday. I made them the night before and poured cauldrons of care into getting the recipe just right. I designed the cakes to have a layer of caramely goodness and to be reeeeally dark chocolatey, soft, and perfectly cakey. I also designed them to be GREAT alongside coffee. And they were a huge success! So I wrapped them in tin foil, packed up my stuff yesterday morning, hopped on the train, met the moustachiod wizard, and guess what I realized when I got there? That I’d left the cakes at home. I found them in the fridge when I got home. Quelle disastre :-/ Hashtag: facepalm. Oh well, if you’re reading this moustachiod wizard, know that I ate a couple of these cakes in your honor this morning, that I owe you some cakes, and that I shall very soon deliver them. But in the meantime, here’s the recipe!
